IMPRovEM ENT. `IN LAM P-sHADEs.

Specification forming part of Letters Patent No. 59.566, dated November13, 1866.

To all whom it may concern Be it known that I, JAMES V. DUNLAP, ofHartford, in the State of Connecticut, have invented, made, and appliedto use, a certain new and useful Improvement in Lamp-Shades; and I dohereby declare the following' to be a full, clear, and exact descriptionof the said invention, reference being had to the annexed drawings,making part of this specication, wherein Figure l is a section of theshade and holder, and Fig. 2 is a plan of said holder.

Similar letters denote the same parts.

Lamp-shades have heretofore been made with a folded paper cone,connected at the upper end by a ring or annulus applied to a holder thatsets upon the lamp-chimney, as shown in the patent of C. St. John,October 17, A. D. 1856. Inv this the wire ring that unites the folds ofpaper at theupper end of the shade is very apt to tear through the paperin putting the shade upon or taking it off the holder 5 and the wiresthat attach the holder to the chimney have, in these articles, usuallybeen separate pieces', extending up from the ring ofthe holder, and wereliable to slip aside on the glass chimney and prevent the shade standingcorrectly in position.

The nature of my said invention consists in a holder for lamp-shadesformed with bent wire springs, that are united in pairs at or near themoving ends of the springs that take the chimney, so that said sprin gsare free to yield to accommodate the chimney, but cannot slip aside uponthe same. I also line the paper shade with muslin or similar wovenmaterial at and near the point where the annulus passes through the.folds of the shade, so as to prevent the same tearing out when in use.

In the drawings, a represents the paper shade, formed of a strip ofpaper folded, and through holes at one edge a Wire ring or annulus, b,passes, the said paper being united at its ends to form a shade.

The shade is lined with muslin where the holes are perforated for theannulus b, and said lining may extend a greater or less distance downthe paper shade.

c is a metal ring, from which the Wires d d rise. These are formed inpairs, the ends of the wires being attached to the ring c.

The wires d are bent so as to leave an offset at l l for the annulus toset into, a curved surface at 2 2 to set against the sides of thechimney, and the connecting radial bends at 8 3, which, joining theWires at their upper ends in pairs, prevents them slipping sidewise uponthe smooth glass chimney when applied to the same.

The bends at 3 3 stand nearly radially of the holder, in order that thewires may pass into the folds of the paper shade when that shade istaken oft' the holder and folded together into a compact form andinserted into the holder-ring c, so that the shade and holder assume avery compact form for transportation.

In this mode of construction there are no loose ends to the springs ofwire; hence the shade is not likely to be injured.

I find that the muslin or similar woven Inaterial has to be applied tothe strip of paper forming the shade after the same has been folded, inorder that the exterior of the shade may appear uniform. I thereforeapply the slip of muslin to the edge of the folded paper (which at thetime is drawn out straight) and after the paste has become sufficientlydry the shade is folded up together, and the hole for the annulus has tobe bored through the material by a drill while such material is held inclamp or holder. This mode of applying the muslin or cloth renders theshade sufficiently strong at the annulus without there being any changein the appearance of the folds on the outside.

What I claim, and desire to secure by Letters Patent, is

The shade-holder formed with wire springs that are made in pairs, unitedat their upper ends, in the manner and for the purposes set forth.

In witness whereof I have hereunto set my signature this 23d day of June A. D. 1866.
